COMBINED CAST-STEEL AND WROUGHT-IRON YOKE.

Specification of Letters Patent.

-Patented Mar. 9, 1915.

Application filed March 23, 1914. Serial No. 826,807.

To (1.! whom it may; concern lie it known that I, ALFRED CoPoNY, asubject of the Emperor of Austria-Hungary, residing in Chicago, in thecounty of Cook and State of Illinois, have invented a new gings which iscomposed partly of steel castings and partly of wrought iron, the partsbeing so arranged that the yoke embodies all the advantages ofthe twodifferent kinds of metal of which it is made.

Another object of the invention is to pro vide a combined cast steel andwrought iron yoke which may be used in a horizontal position andattached to the coupler by means of a connecting kcy..

The invention furthermore consists in the improvements in the parts anddevices and in the novel combinations of the parts and devices hereinshown, described or claimed.

in the drawing forming a part of this specification, Figure l is a sideelevation of one form of yoke embodying my improve ments. Fig. 2 is atop plan view of the structure shown in Fig. 1. Figs..3 and 4 arevertical, sectional views taken on the lines 3 3 and respectively ofFig. Fig. 5 is a rear end elevation of the yoke. Fig. (3 is a sideelevation of another form of yoke enibodyinglny improvements. Fig. 7 isa top plan view of the structure shown in Fig. Fig. 9 is a vertical,sectional view taken on the line 88 of Fig. 7 and Fig. 9 is a rear endelevation of the yoke shown in Figs. 6 and 7.

Referring now more particularly to the form of yoke shown in Figs. 1 to5 inclusive. 10, 10 denotetwo pieces of wrought iron, each of whichforms a side arm of the yoke and a pin i' .l'urear portion thereof. Eachst ap of wrought iron has two horizontally extending portions 11 andacurved, bent end 12 which encircles an elongated boss 13 on the outerside of the steel casting 14, the castings 14 being each provided with alongitudinally extending slot 15 adapted to receive a coupler connectingkey therethrough. Each casting 1d, on its inner face,

is beveled 'as shown at 16.16 to provide'for freedom of movement betweenthe yoke and, coupler. The rear ends of the wrought iron straps 1O abuteach other in the'central line of the yoke, as indicated at 17 and thetwo pieces of wrought iron are firmly and rigidly connected to eachother by means of a wrought iron clip 18 ha ing tongues 19'benttherearound and brought together on the rear side. of the yoke; asindicated at '20. The clip 18, as clea. ly shown in the draw ing', alsoforms a filler at the rear end of the yoke against which the rearfollower of the draft rigging ma abut and be moved. thereby.

In the structure shown more particularly .in Figs. 6' to 9 inclusi e,two straps of wrought iron 110, 110, are used, each of which. at itsforward end. is bent around and encircles an elongated boss 113 on a isfurthern'iore provided on its inner side.

with beveled faces 11%, 116. The rear'ends of the wrought iron strapsare brought together as indicated at 117 and the same are securedtogether by means of a filler plate 118 secured thereto by rivets 121.In the structure shown in F igs. G to 9.; it will be noted that thewidth of the yoke through out the lengths of both arms andrear portionthe same. thus differing somewhat from the yoke shown. in Figs 1 to 5inclusive where the curved end portions of the wrought iron straps areoliset where the same encircle the bosses of the steel castings. Tomaintain the vertical width of the arms of the yoke constant throughoutits length, portions of the metal thereof are upset, as indicated at 122where the straps encircle the bosses of the steel castings;

From the rufeceding description it will be seen that I have provided acombined cast steel and wrought iron yoke which may be used in ahorizontal'position and detachably connected to a coupler by zneans ofan ordi nary connecting key, the yokepossessing all the advantages of awrought iron strap which has greatest strength under tension and yetwhich will not be ilistorted or upset by the coupler connecting keyunder draft inasmuch as. the key contacts directly with the steelcastings ich is well adapted to resist lthestrains placed thereupon. Theyoke isfurthermore-of simple construction and may be manufactured atrelatively small expense.

Although I have herein shown and described what I now consider thepreferred embodiment of my improvements, yet it'will be Understood thatvarious changes and modifications may be made without departing from thespirit of the invention, and all such changes and modifications arecontemplated as come within the scope of the.

claims appended hereto.

I claim:-

1; A yoke for railway draft. arscomprising two slotted cast pieces eacliof which is provided witha boss, the slots extending through the bosses,and two wrought-iron straps each of which is doubledupon itself gearscomprising two wrought iron straps each of which is doubled upon itselfand provided with an elongated recess located at the front endsof theyoke arms, the por: tions of each strap to the rear of said-recessesformed therein being brought together and a east member secured to eachof said straps, each cast member having a boss seated within theelongated recess of the corresponding wrought iron straps.

3. A yoke for railway draft gears comprising two cast steel end pieceseach of which is slotted to receive a couplerconnecting key and providedwith an elongated boss, two straps of wrought iron, each of whichisbentaround a boss of one of said cast-pieces, said wrought iron strapshaving their rear ends bent to form the rear portion of the yoke, andmeans for rigidly connecting the rear bent ends of said wrought ironstraps, substantially as specified.

Signed this 13 day of'March, 1914, in the presence of two subscribingwitnesses.
